NTN tapered roller bearings are components designed to support combined radial and axial loads. Their raceway and roller geometry allows linear contact that distributes the load and provides high load capacity. They are used in applications requiring precision and rigidity, such as transmission boxes, gearboxes, wheel axles and industrial machinery. MR Accesorios Industriales sells this line for the Argentine market.
The designation of these bearings combines a series number and a suffix that identifies the design. For example, in 4T-2688†/2631, the prefix 4T indicates the series, followed by the cone and cup numbers separated by a slash. The letter J may appear in some variants. Examples such as 4T-05079†/05185 or 4T-15106†/15245 show the diversity of sizes. Learn more about how to interpret these codes by consulting our technical team.
These bearings are used in industries such as automotive, metallurgical, food and mining. In Argentina, they are common in transport equipment, mills, presses and agricultural machinery. Their ability to support combined loads makes them suitable for demanding applications. MR Accesorios Industriales offers them for replacement and new projects.
To select the correct bearing, take into account radial and axial load, operating speed and environmental conditions. Mounting requires precise alignment and adequate lubrication. Sealing will depend on environmental contamination. Incorrect fitting can reduce service life. Consult our specialists to choose the optimal configuration for your equipment.
There are equivalences between brands for tapered roller bearings, but it is essential to verify dimensions and tolerances. NTN offers a wide range that can be interchanged with other leading brands. If you have the code from another brand, we can indicate the compatible alternative. Interchangeability must be technically validated to ensure performance.
